or something in my Windows MinGW/CMake (2.8.8) is not working.
BACKGROUND: http://www.cmake.org/cmake/help/v2.8.8/cmake.html#command:include_directories specifies:"Add the given directories to those the compiler uses to search for include files."
I'm working on a project that compiles in Linux and I am trying to get it to compile on Windows using MinGW. The open source project is Scribus - a layout program much like Adobe PageMaker and Adobe InDesign. The Scribus project uses CMake. I've confirmed that in the topmost CMakeLists.txt file of the Scribus source code, there is the dependency project Cairo [graphics]and that Cairo has as its destination "include" directory "/build32/include/cairo" specified. Moreover, at the end of the CMake Configure, I have a MESSAGE statement that displays the value of INCLUDE_DIRECTORIES, and indeed "/build32/include/cairo"
is therein.I added a SET statement, just in case, to the topmost Scribus source CMakeLists.txt file:
MESSAGE("Finding CAIRO...")
FIND_PACKAGE(CAIRO)
IF(CAIRO_FOUND)
MESSAGE("CAIRO Library Found OK")
SET(CAIRO_INCLUDE_DIR /local32/include/cairo)
MESSAGE("Setting CAIRO_INCLUDE_DIR = ${CAIRO_INCLUDE_DIR}")
and the MESSAGE statement duly produces the expected result
at Configure time in the CMake GUI (invoked with "mingw32-make edit_cache"):
Finding CAIRO...
CAIRO Library Found OK
Setting CAIRO_INCLUDE_DIR = /local32/include/cairo
Near the very end of the Configure session,
I also print out what the INCLUDE_DIRECTORIES
has just to make sure something has not altered. My understanding
is that INCLUDE_DIRECTORIES is like a hash table that you continue
to append to and that nothing is deleted from it and that it's values
will appear (or made available to?) on the compile command line.
Here's the code the shows what the value is near the completion of
Configure:
get_property(inc_dirs DIRECTORY PROPERTY INCLUDE_DIRECTORIES)
message("inc_dirs = ${inc_dirs}")
and here is the result:
inc_dirs =
C:/QT/4.8.2/include;C:/QT/4.8.2/include/QtOpenGL;C:/QT/4.8.2/include/QtWebKit;C:/QT/4.8.2/include/QtGui;C:/QT/4.8.2/include/QtXml;C:/QT/4.8.2/include/QtNetwork;C:/QT/4.8.2/include/QtCore;/local32/include/freetype2;C:/MinGW1/build32/scribus32;C:/MinGW1/build32/scribus32/scribus;C:/QT/4.8.2/include/ActiveQt;C:/QT/4.8.2/include/ActiveQt;C:/QT/4.8.2/include/QtDesigner;C:/QT/4.8.2/include/ActiveQt;C:/QT/4.8.2/include/ActiveQt;C:/QT/4.8.2/include/QtDeclarative;C:/QT/4.8.2/include/QtScriptTools;C:/QT/4.8.2/include/QtDBus;C:/QT/4.8.2/include/QtDesigner;C:/QT/4.8.2/include/QtXml;C:/QT/4.8.2/include/QtSql;C:/QT/4.8.2/include/QtOpenGL;C:/QT/4.8.2/include/QtMultimedia;C:/QT/4.8.2/include/QtNetwork;C:/QT/4.8.2/include/phonon;C:/QT/4.8.2/include/QtXmlPatterns;C:/QT/4.8.2/include/QtWebKit;C:/QT/4.8.2/include/QtHelp;C:/QT/4.8.2/include/QtUiTools;C:/QT/4.8.2/include/QtTest;C:/QT/4.8.2/include/QtScript;C:/QT/4.8.2/include/QtSvg;C:/QT/4.8.2/include/Qt3Support;C:/QT/4.8.2/include/QtGui;C:/QT/4.8.2/include/QtCore;C:/QT/4.8.2/mkspecs/default;C:/QT/4.8.2/include;C:/QT/4.8.2/include/QtCore;/local32/include/cairo;/local32/include;C:/MinGW1/build32/lcms2-2.3/include;C:/MinGW1/local32/include/libxml2;C:/MinGW1/local32/include;C:/MinGW1/local32/bin
What I am seeing is that although Configure reports the inclusionof the Cairo "include" directory, the path, nor any of the paths, does not show up in the
code that ultimately gets compiled.QUESTION: How do I specify an include directory path that will appear on the command line at compilation time?
