[CMake] CMake toolchain file changing shared library loading name

[Дмитрий Дороговцев]

Hello.
I have a strange issue when cross compiling with CMake.
When i compile for host, in the resulting binary i have:

readelf -d ./test
...
0x00000001 (NEEDED)          Shared library: [libfoo.so]
0x0000000f (RPATH)              Library rpath: [$ORIGIN/../../lib/]
...

When i use CMake toolchain file (cmake -DCMAKE_TOOLCHAIN_FILE=arm_
test.cmake .) i have:
readelf -d ./test
...
0x00000001 (NEEDED)          Shared library:
[/home/mgh/proj/test/lib/libfoo.so]
0x0000000f (RPATH)              Library rpath: [$ORIGIN/../../lib/]
...

My toolchain file is very simple:

set( CMAKE_SYSTEM_NAME armLinux )

set( CMAKE_C_COMPILER arm-linux-gnueabi-gcc )
set( CMAKE_CXX_COMPILER arm-linux-gnueabi-g++ )
set( CMAKE_FIND_ROOT_PATH /home/mgh/toolchains/arm-linux-gnueabi/bin )

So my question is why path to libfoo.so has been changed in executable after
cross compiling? Thank you.
