# CheckCXXSourceCompiles.cmake. Actually it should be used by all macros which
# use TRY_COMPILE() or TRY_RUN().
# It takes the CMAKE_REQUIRED_LIBRARY variable and searches it for imported
# (library) targets. Since the project created by TRY_COMPILE() (and TRY_RUN())
# does not know about these imported targets, this macro here replaces these
# imported targets with the actual library files on disk and it also
# adds the libraries from the link interface of these imported targets.
# E.g the imported target KDE4__kdeui is replaced on my system with /opt/kdelibs/lib/libkdeui.so
# and the link interface libraries, which includes e.g. /opt/kdelibs/lib/libkdecore.so.
# This way imported targets work also when used with CHECK_CXX_SOURCE_COMPILES/RUNS().
