Is there a way to set the directory that cmake (2.8) uses for object
file generation? I haven't found an online resource for this.
There is a difference when we build the same project on a Windows
vs. Linux platform.
On WIN32, cmake creates '<PROJ_NAME>/<PROJ_NAME>.dir/ directory for
object files.
On UNIX, cmake creates '<PROJ_NAME>/<PROJ_NAME>.dir/ENTIRE/ABS/PATH/
TO/<PROJ_NAME> directory for object files.
I only can reproduce this behavior if I have sources which are NOT
under the top-level source directory, i.e. something like this:
$HOME/projects/super-duper/CMakeLists.txt:
#--------------------------------------------
cmake_minimum_required(VERSION 2.8)
project(test)
add_executable(test $env(HOME)/external/test.cxx)
#--------------------------------------------
Am I assuming correctly that that's what you're doing? In that case
you could do something like this:
#-------------------------------------------
# - Create include-wrappers for external source files
#
# CREATE_INCLUDE_WRAPPERS(SRCVAR file1 ...)
#
# The variable SRCVAR will contain a list of source files suitable to
# pass to add_library or add_executable.
#
function(create_include_wrappers srcvar)
if(UNIX)
set(srcs)
# loop over all additional arguments
foreach(s ${ARGN})
# get absolute path
get_filename_component(as "${s}" ABSOLUTE)
# relative path w.r.t toplevel-source directory
file(RELATIVE_PATH rs "${CMAKE_SOURCE_DIR}" "${as}")
# if it begins with .. it is external
if(rs MATCHES "^\.\.")
# this is an external source
# get the basename
get_filename_component(rw "${s}" NAME)
# append it to the current binary directory (might need
something better here)
set(w "${CMAKE_CURRENT_BINARY_DIR}/wrappers/wrapped_${rw}")
# prepare variable for the configured file
set(EXTERNAL_SOURCE "${as}")
# configure the wrapper
configure_file("${CMAKE_SOURCE_DIR}/CMake/
wrapper_template.in" "${w}" @ONLY)
# append the wrapper to the list of source files
list(srcs APPEND "${w}")
else()
# if it's not external, simply append
list(srcs APPEND "${s}")
endif()
endforeach()
else()
# Presumably we don't need the wrappers on non-UNIX
set(srcs "${ARGN}")
endif()
# propagate the list of source files to the caller scope
set(${srcvar} "${srcs}" PARENT_SCOPE)
endfunction()
#-------------------------------------------
The file ${CMAKE_SOURCE_DIR}/CMake/wrapper_template.in could look
somthing like this:
/*-------------------------------------------*/
/* AUTOMATICALLY GENERATED! DO NOT EDIT */
#include "@EXTERNAL_SOURCE@"
/*-------------------------------------------*/
However, such a scheme will slow down configuration and compilation.
