# - Finds both release and debug versions of a library
|
||
#
|
||
# FIND_RELEASE_AND_DEBUG(<prefix> NAMES <library names>
|
||
# [DEFAULT_SUFFIXES | DBG_SUFFIXES <suffixes> ]
|
||
# [PATHS <search paths>] [FIXED_PATHS <fixed paths>])
|
||
#
|
||
# Helps in finding distinct release and debug versions of a library so that
|
||
# the appropriate version is selected according to the build configuration.
|
||
# Assumes that the name of the debug version is that of the release version
|
||
# plus a certain suffix such as "_debug". The effective set of names used
|
||
# to find the debug version is the cartesian product of the library's names
|
||
# and the debug suffixes.
|
||
#
|
||
# Requires the CMake modules SelectLibraryConfigurations (introduced in CMake
|
||
# 2.8.0) and CMakeParseArguments (introduced in CMake 2.8.3).
|
||
#
|
||
# Macro arguments:
|
||
# <prefix> - A prefix for the variables that will be generated.
|
||
# <library names> - non-empty list with the possible names for a library.
|
||
# DEFAULT_SUFFIXES - use the default list of suffixes for finding the debug
|
||
# libraries. The suffixes are: -d, -debug, d, _d, debug
|
||
# <suffixes> - custom non-empty list with specific debug suffixes.
|
||
# <search paths> - optional list with additional path in which the libraries
|
||
# will be search. By default the "lib" suffix for each path
|
||
# is also searched.
|
||
# <fixed paths> - optional list with fixed path guesses (i.e. those which
|
||
# are baked-in into the CMake file.) If the paths contain
|
||
# variables which may change at runtime, they should be
|
||
# specified as <search paths> instead.
|
||
#
|
||
# This macro will generate the following advanced variables:
|
||
# <prefix>_LIBRARY_RELEASE - the release version of the library
|
||
# <prefix>_LIBRARY_DEBUG - the debug version of the library
|
||
# <prefix>_LIBRARY, <prefix>_LIBRARIES - set according to the CMake macro
|
||
# select_library_configurations(...)
|
||
#
|
||
# A minimal example, to look for the library "foo" using the default debug
|
||
# suffixes:
|
||
# FIND_RELEASE_AND_DEBUG(FOO NAMES foo DEFAULT_SUFFIXES)
|
||
#
|
||
# Search for the "foo" library with custom names and suffixes. In this example
|
||
# the release version can be either "foo" or "myfoo". The actual debug version
|
||
# searched is one of "foo-d", "myfoo-d", "foo-dbg" or "myfoo-dbg". The paths
|
||
# "/path1" and "/path2/foo" are also searched.
|
||
# FIND_RELEASE_AND_DEBUG(FOO NAMES foo myfoo DBG_SUFFIXES -d -dbg PATHS /path1 /path2/foo)
