set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}") 完成以上步骤后,CMake将能够找到并正确配置OpenMP_C和OpenMP_CXX。 OpenMP是一种支持并行计算的编程模型,它可以在共享内存系统中实现多线程并行计算。它的优势包括简单易用、跨平台、可移植性强等。OpenMP适用于各种并行计...

cmake增加对openmp的支持 在CMakeList.txt中增加: FIND_PACKAGE( OpenMP REQUIRED) if(OPENMP_FOUND) message("OPENMP FOUND") set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}") set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}") ...
在Windows上使用CMake编译FFTW(OpenMP)的步骤如下: 首先,确保你已经安装了CMake和MinGW-w64(或者其他支持OpenMP的编译器)。你可以从官方网站下载并安装它们。 下载FFTW源代码包。你可以从FFTW的官方网站(https://www.fftw.org/download.html)上找到最新的稳定版本。解压缩下载的源代码包到一个合适的目录。
