CMake

Expand includes and defines transitively in 'external' genexes. This means that we can use expressions of the form $<TARGET_PROPERTY:foo,INTERFACE_INCLUDE_DIRECTORIES> to get a list of the interface include directories of foo, including those coming from dependencies. We can't have a test of a target which has a single include directory in its INCLUDE_DIRECTORIES because the shell on the MSYS platforms transforms a single include directory to include a prefix, which is not what the test expects. We test a target with two directories instead as a means to test a target with no link dependencies. 2013-02-13 15:35:31 +04:00
