kjs/CMakeLists.txt change on KDE-4.0 branch breaks build -- apparent cmake bug?

[Bernhard Rosenkränzer]

Hi,
current KDE-4.0 branch doesn't build here after the recent kjs/CMakeLists.txt 
change:

-- Found PCRE: /usr/include/pcre
-- Looking for PCRE_CONFIG_UTF8
-- Looking for PCRE_CONFIG_UTF8 - not found.
-- Looking for PCRE_CONFIG_STACKRECURSE
-- Looking for PCRE_CONFIG_STACKRECURSE - not found.
CMake Error: Your libPCRE is too old. KJS requires at least PCRE4.5

My PCRE is 7.5, and does define PCRE_CONFIG_UTF8 and 
PCRE_CONFIG_STACKRECURSE - looking at CMakeError.log shows

Determining if the PCRE_CONFIG_UTF8 exist failed with the following output:
/usr/bin/gmake -f CMakeFiles/cmTryCompileExec.dir/build.make 
CMakeFiles/cmTryCompileExec.dir/build

error: pcre.h: No such file or directory

For some reason, -I/usr/include/pcre didn't get added to the compiler flags 
even though it was detected correctly. Adding a
message(STATUS "PCRE headers are in ${PCRE_INCLUDE_DIR}") just before 
include_directories(${PCRE_INCLUDE_DIR}) shows the variable is set correctly.


Is there any known reason why cmake wouldn't be adding this include?
