This works:
set( project_count 0 CACHE INTERNAL "")
function( define_project )

set( project_count ${count} CACHE INTERNAL "")
endfunction()
define_project()

define_project()

It prints out

Re: [CMake] Question about variables, cache, and scope
Calling a function pushs a new variable scope. All variables visible in the
callers scope are copied into the new scope but changes by default only
affect the callee scope. You could try using the PARENT_SCOPE option to the
set command but I'm not sure that will achieve what you want as it only gets
you to the next scope whereas you really want a global variable.
You can use properties instead of variables as those are explicitly scoped.
So something like this:
set_property(GLOBAL PROPERTY project_count "0")
function( define_project ... )
get_property(old_count GLOBAL PROPERTY project_count)
math( EXPR new_count "${old_count}+1" )
set_property(GLOBAL PROPERTY project_count "${new_count}"
endfunction()
will probably work.

[CMake] CTest print output value
Hi ,
I would like to generate a txt report including
various informations produced by each test execution.
my ideas was in a second step to post this cover test onto a cdash portal.
My CMakeLists.txt produce a well formed CTestTestfile.cmake file with the
following a classical structure :
ADD_TEST(Phase1_oconnell "bin/Linux/toulbar2"
"/home/validation/default/oconnell.wcsp" "-B=0" "-v" "-e:")
SET_TESTS_PROPERTIES(Phase1_oconnell PROPERTIES PASS_REGULAR_EXPRESSION
"Optimum: " TIMEOUT "100")
i would like to catch the stdout line produced by the test execution
the standard output print :
=
Optimum: 328 in 15 backtracks and 15 nodes and 0 seconds.
end.
=
how can i do to respectively catch foreach test the following informations ;
${Optimum}
${backtracks}
${nodes}
${seconds}
my ideas is generate a csv files and post it on the dashboard after post
processing.
report exemple : cat report.txt
test;optimum;backtracks;nodes;seconds;
Phase1_oconnell;328;15;15;0;
thanks ,
sincerely Mohamed

[CMake] Question about variables, cache, and scope
I have a function that I define in my top-most CMakeLists.txt file (on
Windows using CMake version 2.8.6) called define_project() that calls
add_executable, sets up compile defintions, etc etc.
For each time define_project() is called *anywhere* in the directory
hierarchy, I need to increment a global "project_count" variable to keep
track of how many projects were created and print that at the very end of
the root CMakeLists.txt file.
So far my attempts at this have been unsuccessful. I tried creating a cache
variable in the root script:
set( project_count 0 CACHE INTERNAL "" )
Then inside of my function, I do this:
function( define_project ... )
math( EXPR count "${project_count}+1" )
set( project_count ${count} )
endfunction()
However, 'project_count' is always 0 each time that the function is
executed.
How can I make this work?

Yes.

Yes.
Having different include paths for different object files would be sufficient
to include all in the same application.
Cmake can do this fine.

Libraries on Windows behave differently because of the .lib/.dll split.
The details are in the install(TARGETS) documentation.

And it only works in Linux (Ubuntu Lucid 10.04 native with CMake 2.8.5
or cross compiling with ptxdist). On Windows XP with VS 2009 and CMake
2.8.5 the following happens:
install(TARGETS ${PROJECT_NAME}-shared EXPORT ${PROJECT_NAME}-targets
LIBRARY DESTINATION "lib")
#install(TARGETS ${PROJECT_NAME}-shared EXPORT ${PROJECT_NAME}-targets
DESTINATION "lib")
install(EXPORT ${PROJECT_NAME}-targets DESTINATION
"lib/cmake/${PROJECT_NAME}")
With the first line used it gives the following error:
CMake Error at src/CMakeLists.txt:19 (install):
install Library TARGETS given no DESTINATION!
Commenting in the first line and using the second (removing the LIBRARY
keyword from the line) configure and build works. If someone wants to
reproduce: this is in my forked tree of the iniparser library, you could
get it from GitHub here: https://github.com/LeSpocky/iniparser/tree/work
