[CMake] problem with ADD_DEFINITION

[Nuno Lopes]

Hello,

I'm new to cmake and I'm trying to port one of my projects to cmake, but I'm
having some difficulties with this:

# libxml2
PKGCONFIG( libxml-2.0 XML_INCLUDE_DIR XML_LIBRARY_DIR XML_LINK_FLAGS
XML_CFLAGS)
IF( NOT XML_INCLUDE_DIR )
    MESSAGE("WARNING: libxml2 is not installed.")
ELSE( NOT XML_INCLUDE_DIR )
    # Add libXML2 stuff
    LINK_LIBRARIES(${XML_LINK_FLAGS})
    ADD_DEFINITIONS(${XML_CFLAGS})
ENDIF( NOT XML_INCLUDE_DIR )


XML_CFLAGS is set to: -I/usr/include/libxml2

after running "cmake ." (2.4.2) with no errors/warnings, make fails with the
following message:

Frameworks/Communication/CMakeFiles/Communication.dir/flags.make:5: ***
missing separator.  Stop.
make[1]: *** [Frameworks/Communication/CMakeFiles/Communication.dir/all]
Error 2
make: *** [all] Error 2


the contents of that file:
# CMAKE generated file: DO NOT EDIT!
# Generated by "Unix Makefiles" Generator, CMake Version 2.4

CXX_FLAGS
= -DCommunication_EXPORTS   -fPIC -I/socrob/co/common/Frameworks/Predicates
-I/socrob/co/common/Frameworks/StateMachine -I/socrob/co/common/Frameworks/Communication
 -I/socrob/co/common/Frameworks/Data -I/socrob/co/common/Frameworks/Logging
-I/socrob/co/common/Frameworks/Math -I/socrob/co/common/Frameworks/ObjectFunctions
 -I/socrob/co/common/Frameworks/SocRobXML -I/socrob/co/common/Frameworks/Support
 -I/socrob/co/common/Components/Cortex/TeamOrganizer -I/socrob/co/common/Components/Cortex/BehaviorCoordinator
 -I/socrob/co/common/Components/Cortex/BehaviorExecutor -I/socrob/co/common/Components/EventManager
 -I/socrob/co/common/Components/WorldInfo
 -I/usr/include/libxml2


So the problem is that there is a newline before the libxml2 cflags. Is this
a bug in cmake or am I just doing something wrong?

Thanks in advance,
Nuno Lopes
