"Library not loaded: @rpath/libgpr.dylib" when running tests/example

[bramp]

cmake .
make

then

$ ./all-tests
dyld[97154]: Library not loaded: @rpath/libgpr.dylib
  Referenced from: /Users/bramp/gpr/all-tests
  Reason: tried: '/usr/local/lib/libgpr.dylib' (no such file), '/usr/lib/libgpr.dylib' (no such file)
Abort trap: 6

Same issue with ./parse-gcode.

I don't understand dynamic linkers enough, but this is on a Mac.

Hmmm I normally run on Mac and I don't see this problem. Where is libgpr.dylib installed when you build?

[bramp]

To be clear, I didn't do make install, just make.

$ find .

Interestingly, after posting this bug, I created my own CMakeLists.txt in a parent directory

project(app)

cmake_minimum_required (VERSION 2.8.12)

set (CMAKE_CXX_STANDARD 11)
add_subdirectory(gpr)
add_executable(app main.cpp)
target_link_libraries(app gpr)

and that does run successfully, while using your library.
