У меня есть модульные тесты, написанные с использованием CTest, которые зависят от реализации Intel MKL BLAS. Я использую find_package(BLAS) и связываю исполняемые файлы теста с ${BLAS_LIBRARIES}. Исполняемые файлы теста зависят от DYLD_LIBRARY_PATH для поиска библиотек mkl, а не от встроенного LC_RPATH.
К сожалению, из-за SIP DYLD_LIBRARY_PATH не распространяется в среду ctest, поэтому, когда он пытается запустить тесты, он не может связать библиотеки mkl.
Есть ли способ заставить CMake встроить внешний LC_PATH для тестовых исполняемых файлов в каталог сборки?
Вот базовый исполняемый файл теста (test.cpp)
#include <mkl_cblas.h>
int main() {
return &cblas_dgemm != nullptr;
}
и вот связанный CMakeLists.txt
cmake_minimum_required(VERSION 3.14.5)
project(blas LANGUAGES CXX)
include(CTest)
set(BLA_VENDOR Intel10_64lp_seq)
find_package(BLAS REQUIRED)
add_executable(test_blas test.cpp)
target_link_libraries(test_blas ${BLAS_LIBRARIES})
add_test(NAME test_direct COMMAND test_blas)
Нахожу MKL и собираю без проблем.
