I have it basically working here now, including a cmake.m4 macro so you can do CMAKE_CHECK_MODULE() in configure.in. Checking whether a package has been found is straightforward. For creating the compile flags I'm using localGen->GetIncludeFlags(language.c_str(), false); For the linking I currently get the FOO_LIBRARIES variables, create an empty executable target, set the LINKER_LANGUAGE to what the user wants, add all the libraries to the executable and then call localGen->GetTargetFlags() This is what I get currently, the stuff for libxml2 is from cmake via FindLibXml2.cmake (with an additional libbar.so): ~/src/tests/pkgconfig/pkgconfig> ./configure checking for pkg-config... /usr/bin/pkg-config checking pkg-config is at least version 0.9.0... yes checking for QtSQL... yes Result: CFLAGS: -DQT_SHARED -I/usr/include/QtSql -I/usr/include/QtCore LIBS: -lQtSql -lQtCore checking for QtXML... yes Result: CFLAGS: -DQT_SHARED -I/usr/include/QtXml -I/usr/include/QtCore LIBS: -lQtXml -lQtCore checking for XFT... yes Result: CFLAGS: -I/usr/include/freetype2 LIBS: -lXft checking for LIBXML2...
