Had to make my own portaudio and rtl-sdr binaries. The available packages weren't compatible somehow. Also wxWidgets wxPack doesn't include OpenGL support but it's easy enough to compile.

# FindPackageHandleStandardArgs
|
|
# -----------------------------
|
|
#
|
|
#
|
|
#
|
|
# FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ... )
|
|
#
|
|
# This function is intended to be used in FindXXX.cmake modules files.
|
|
# It handles the REQUIRED, QUIET and version-related arguments to
|
|
# find_package(). It also sets the <packagename>_FOUND variable. The
|
|
# package is considered found if all variables <var1>... listed contain
|
|
# valid results, e.g. valid filepaths.
|
|
#
|
|
# There are two modes of this function. The first argument in both
|
|
# modes is the name of the Find-module where it is called (in original
|
|
# casing).
|
|
#
|
|
# The first simple mode looks like this:
|
|
#
|
|
# ::
|
|
#
|
|
# FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name>
|
|
# (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )
|
|
#
|
|
# If the variables <var1> to <varN> are all valid, then
|
|
# <UPPERCASED_NAME>_FOUND will be set to TRUE. If DEFAULT_MSG is given
|
|
# as second argument, then the function will generate itself useful
|
|
# success and error messages. You can also supply a custom error
|
|
# message for the failure case. This is not recommended.
|
|
#
|
|
# The second mode is more powerful and also supports version checking:
|
|
#
|
|
# ::
|
|
#
|
|
# FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME
|
|
# [FOUND_VAR <resultVar>]
|
|
# [REQUIRED_VARS <var1>...<varN>]
|
|
# [VERSION_VAR <versionvar>]
|
|
# [HANDLE_COMPONENTS]
|
|
# [CONFIG_MODE]
|
|
# [FAIL_MESSAGE "Custom failure message"] )
|
|
#
|
|
# In this mode, the name of the result-variable can be set either to
|
|
# either <UPPERCASED_NAME>_FOUND or <OriginalCase_Name>_FOUND using the
|
|
# FOUND_VAR option. Other names for the result-variable are not
|
|
# allowed. So for a Find-module named FindFooBar.cmake, the two
|
|
# possible names are FooBar_FOUND and FOOBAR_FOUND. It is recommended
|
|
# to use the original case version. If the FOUND_VAR option is not
|
|
# used, the default is <UPPERCASED_NAME>_FOUND.
|
|
#
|
|
# As in the simple mode, if <var1> through <varN> are all valid,
|
|
# <packagename>_FOUND will be set to TRUE. After REQUIRED_VARS the
|
|
# variables which are required for this package are listed. Following
|
|
# VERSION_VAR the name of the variable can be specified which holds the
|
|
# version of the package which has been found. If this is done, this
|
|
# version will be checked against the (potentially) specified required
|
|
# version used in the find_package() call. The EXACT keyword is also
|
|
# handled. The default messages include information about the required
|
|
# version and the version which has been actually found, both if the
|
|
# version is ok or not. If the package supports components, use the
|
|
# HANDLE_COMPONENTS option to enable handling them. In this case,
|
|
# find_package_handle_standard_args() will report which components have
|
|
# been found and which are missing, and the <packagename>_FOUND variable
|
|
# will be set to FALSE if any of the required components (i.e. not the
|
|
# ones listed after OPTIONAL_COMPONENTS) are missing. Use the option
|
|
# CONFIG_MODE if your FindXXX.cmake module is a wrapper for a
|
|
# find_package(... NO_MODULE) call. In this case VERSION_VAR will be
|
|
# set to <NAME>_VERSION and the macro will automatically check whether
|
|
# the Config module was found. Via FAIL_MESSAGE a custom failure
|
|
# message can be specified, if this is not used, the default message
|
|
# will be displayed.
|
|
#
|
|
# Example for mode 1:
|
|
#
|
|
# ::
|
|
#
|
|
# find_package_handle_standard_args(LibXml2 DEFAULT_MSG
|
|
# LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)
|
|
#
|
|
#
|
|
#
|
|
# LibXml2 is considered to be found, if both LIBXML2_LIBRARY and
|
|
# LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to
|
|
# TRUE. If it is not found and REQUIRED was used, it fails with
|
|
# FATAL_ERROR, independent whether QUIET was used or not. If it is
|
|
# found, success will be reported, including the content of <var1>. On
|
|
# repeated Cmake runs, the same message won't be printed again.
|
|
#
|
|
# Example for mode 2:
|
|
#
|
|
# ::
|
|
#
|
|
# find_package_handle_standard_args(LibXslt
|
|
# FOUND_VAR LibXslt_FOUND
|
|
# REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS
|
|
# VERSION_VAR LibXslt_VERSION_STRING)
|
|
#
|
|
# In this case, LibXslt is considered to be found if the variable(s)
|
|
# listed after REQUIRED_VAR are all valid, i.e. LibXslt_LIBRARIES and
|
|
# LibXslt_INCLUDE_DIRS in this case. The result will then be stored in
|
|
# LibXslt_FOUND . Also the version of LibXslt will be checked by using
|
|
# the version contained in LibXslt_VERSION_STRING. Since no
|
|
# FAIL_MESSAGE is given, the default messages will be printed.
|
|
#
|
|
# Another example for mode 2:
|
|
#
|
|
# ::
|
|
#
|
|
# find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
|
|
# find_package_handle_standard_args(Automoc4 CONFIG_MODE)
|
|
#
|
|
# In this case, FindAutmoc4.cmake wraps a call to find_package(Automoc4
|
|
# NO_MODULE) and adds an additional search directory for automoc4. Here
|
|
# the result will be stored in AUTOMOC4_FOUND. The following
|
|
# FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper
|
|
# success/error message.
