While packaging CMake 2.8.8 for FreeBSD, an old port of lprof [1]
started failing to build after some include headers were not found.
The relevant CMakeLists does the following:
add_library(foo foo.c)
set_directory_properties(
PROPERTIES INCLUDE_DIRECTORIES "${SOME_DIRECTORY}")
foo.c includes "bar.h" which is in ${SOME_DIRECTORY}.
This used to work until commit 9106b564ae5bf0bf1c1ff4a3fca484bcfd40e183,
and the following patch can be applied to master for ctest to fail on
the IncludeDirectories test:
diff --git a/Tests/IncludeDirectories/TargetIncludeDirectories/CMakeLists.txt
b/Tests/IncludeDirectories/TargetIncludeDirectories/CMakeLists.txt
index 2cf36f5..05065c2 100644
--- a/Tests/IncludeDirectories/TargetIncludeDirectories/CMakeLists.txt
+++ b/Tests/IncludeDirectories/TargetIncludeDirectories/CMakeLists.txt

Moving that set_property(DIRECTORY) call somewhere before the
add_executable() call makes the test pass.
Is this change of behaviour intentional?
Cheers.
