Visual studio Cmake和路径

我正在尝试制作OpenVolumeMesh，如中所述。我得到一个错误：

找不到Google测试框架

我已经下载了该框架，并遵循了：

一切都很顺利

a） CMA在哪个地方搜索gtest？ b） 是小路吗？因为我已经复制粘贴了谷歌测试框架的文件夹，但cmake仍然没有找到任何东西

OpenVolume中的findgoogletesting.cmake包含以下内容：

FindGoogleTest.cmake

已经告诉您答案：您应该运行

cmake

，并添加以下标志：

cmake -D GTEST_PREFIX=<path/to/gtest> </path/to/OpenVolumeMesh/sources>

cmake-D GTEST_前缀=
