Summary: SOURCES target property (get_property()) has very
inconsistent result - wildly differing path specifications
Description:
The appended sample yields the following output:
[amoh at lxamoh build]$ cmake ..
tgt_sources
main.cpp;[TEST_ROOT]/get_property_sources_broken_paths/test.rc;blubb.tas
-- Configuring done
CMake Error at CMakeLists.txt:17 (add_library):
Cannot find source file:
blubb.tas
Tried extensions .c .C .c++ .cc .cpp .cxx .m .M .mm .h .hh .h++ .hm .hpp
.hxx .in .txx
-- Build files have been written to:
[TEST_ROOT]/get_property_sources_broken_paths/build
Note the very inconsistent items in the tgt_sources line shown above:
For (I assume) all language-related files a project-*relative* path will be
preserved, whereas for *existing* foreign-language files the *absolute* path to
the project-contained file (due to the result returned by the existence check?)
will be delivered, plus for *non-existing* foreign-language files the *relative*
path will be returned.
Whoa.
Since AFAIK it is recommended practice to add all files within a project to the
target (well, at least *.c* and *.h*, maybe NOT *.rc* and other more foreign
files?), this inconsistency is an annoying PROBLEM if detected, and a very
annoying BUG if undetected.
Thanks!
Steps to Reproduce:
cmake_minimum_required(VERSION 2.6)
project(get_property_sources_broken_paths)
file(WRITE main.cpp "
int main()
{
#include \"get_property_sources_broken_paths.h\"
return 0;
}
")
file(WRITE test.rc "")
#add_executable(get_property_sources_broken_paths main.cpp test.rc blubb.tas)
add_library(get_property_sources_broken_paths SHARED main.cpp test.rc blubb.tas)
get_property(tgt_sources TARGET get_property_sources_broken_paths PROPERTY
SOURCES)
message("tgt_sources ${tgt_sources}")
