I am using ExternalProject_add on windows 7 and I am having difficulty passing in some arguments. I have mocked up an example showing my problem. To summarise:
When I pass a path e.g. "D:/somehere/cool" through with the CMAKE_ARGS args I get out just "D:".
has anyone else come across this?
My example:
[directory layout]
-foo_master
\-CMakeLists.txt <- see Appendix 1.
|-foo_project
\-foo_project.tar.gz <- see Appendix 2.
-foo_master-build
From foo_master-build I run (in a visual studio command window)
cmake -G "NMake Makefiles" ..\foo_master
nmake
The undersirable thing is my foo_it application is installed into
d:\bin\foo_it.exe
rather than
d:\develoopment\foo_install_here\bin\foo_it.exe
Appendix 1. - CMakeList.txt
=============================================
CMAKE_MINIMUM_REQUIRED( VERSION 2.8 )
PROJECT( foo_master )
INCLUDE( ExternalProject )
SET( PLATFORM_BUILD_COMMAND nmake )
SET( PLATFORM_INSTALL_COMMAND nmake install )
# Define FOO_INSTALL_PREFIX somewhere useful
SET( FOO_CMAKE_ARGS -DFOO_INSTALL_PREFIX=D:/development/foo_install_here )
SET( FOO_SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/foo_project )
ExternalProject_Add( build_foo
PREFIX ${CMAKE_CURRENT_BINARY_DIR}
#--Download step--------------
URL ${FOO_SOURCE_DIR}/foo_project.tar.gz
#--Update/Patch step----------
#--Configure step-------------
CMAKE_ARGS ${FOO_CMAKE_ARGS}
#--Build step-----------------
BUILD_COMMAND ${PLATFORM_BUILD_COMMAND}
#--Install step---------------
INSTALL_COMMAND ${PLATFORM_INSTALL_COMMAND} )
=============================================
Appendix 2: - Contents of foo_project.tar.gz, CMakeLists.txt and main.cpp
=============================================
CMAKE_MINIMUM_REQUIRED( VERSION 2.8 )
PROJECT( foo )
MESSAGE( STATUS "FOO INSTALL PREFIX: ${FOO_INSTALL_PREFIX}" )
SET( FOO_INSTALL_PREFIX ${FOO_INSTALL_PREFIX} CACHE PATH "Foo install dir" )
ADD_EXECUTABLE( foo_it main.cpp )
INSTALL( TARGETS foo_it DESTINATION ${FOO_INSTALL_PREFIX}/bin )
=============================================
#include <stdio.h>
int main()
{
printf( "\nExternalProject_Add text parsing test.\n" );
return 0;
}
=============================================
I have attached the tar.gz file in case anybody wants to try it out.
Cheers,
Hugh.
