Public bug reported:
I am trying to build an application which uses PCL on
Ubuntu 17.04 and I am getting CMake linker errors. Here's a minimal
working example:
CMakeLists:
cmake_minimum_required(VERSION 3.3)
project(example)
add_executable(${PROJECT_NAME} main.cpp)
# PCL
find_package(PCL REQUIRED)
target_link_libraries(${PROJECT_NAME} PUBLIC ${PCL_LIBRARIES})
main.cpp is just int main() { return 0; }.
CMake reports this:
CMake Warning at CMakeLists.txt:4 (add_executable):
Cannot generate a safe runtime search path for target example because files
in some directories may conflict with libraries in implicit directories:
runtime library [libmpi.so] in /usr/lib may be hidden by files in:
/usr/lib/x86_64-linux-gnu/openmpi/lib
Some of these libraries may not be found correctly.
Make fails with:
*** No rule to make target '/usr/lib/libmpi.so', needed by 'example'.
I've found a hack-ish remedy for the problem: remove "/usr/lib/libmpi.so" from
VTK_LIBRARIES in
/usr/lib/x86_64-linux-gnu/cmake/pcl/PCLConfig.cmake.
