cmake_minimum_required(VERSION 3.5) project(swipl-pack-environ)

Include swipl.cmake from the running SWI-Prolog's home

list(INSERT CMAKE_MODULE_PATH 0 $ENV{SWIPL_HOME_DIR}/cmake) include(swipl)

Create the library as a CMake module

add_library(environ MODULE c/environ.c)

Link the library to SWI-Prolog. This also removes the lib prefix

from the target on systems that define a common library file prefix

target_link_swipl(environ)

Install the foreign taget. `${swipl_module_dir}` contains the

directory for installing modules for this architecture.

install(TARGETS environ DESTINATION ${CMAKE_CURRENT_SOURCE_DIR}/${swipl_module_dir})

Run tests. This is executed before the pack is installed.

swipl_test(name) runs Prolog with the command line below.

# # swipl -p foreign=${CMAKE_CURRENT_SOURCE_DIR}/${swipl_module_dir} \ # -p library=${CMAKE_CURRENT_SOURCE_DIR}/prolog \ # --on-error=status \ # -g test_${name} \ # -t halt \ # ${CMAKE_CURRENT_SOURCE_DIR}/test/test_${name}.pl # # This implies that a test name must be defined in a file # `test/test_${name}.pl`, which exports a predicate `test_${name}`. The # test succeeds if this predicate succeeds and no error messages are # printed.
