CMake找不到GLEW [英] CMake can't find GLEW

问题描述

我已经读过[1]，但就我而言，CMake说它找不到毛病.

I've read this [1], but in my case CMake says it can't find glew.

我在Windows上，并且我的CMake模块文件夹中有一个FindGLEW.cmake文件，大概是在我安装CMake-3.6时放置的位置.我在sourceforge上找到了GLEW，并下载了Windows的zip文件.我解压缩并安装在C:\ Program Files \ glew中.当我创建了自己的库并使用CMake构建和安装它们时，这是它们安装的默认位置，因此我非常有信心在这里可以.

I'm on Windows and there is a FindGLEW.cmake file in my CMake modules folder, presumably put there when I installed CMake-3.6. I found GLEW on sourceforge and downloaded the zip file for Windows. I unzipped and installed in C:\Program Files\glew. When I've created my own libraries and used CMake to build and install them, this is the default location they are installed to so I am pretty confident I'm OK here.

我的CMakeLists.txt中的代码段是:

The snippet from my CMakeLists.txt is:

find_package(GLEW REQUIRED)
include_directories(${GLEW_INCLUDE_DIRS})
link_libraries(${GLEW_LIBRARIES})

CMake的实际错误消息是:

The actual error message from CMake is:

CMake Error at C:/Program Files/CMake/share/cmake-3.6/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
  Could NOT find GLEW (missing: GLEW_INCLUDE_DIR GLEW_LIBRARY)
Call Stack (most recent call first):
  C:/Program Files/CMake/share/cmake-3.6/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)
  C:/Program Files/CMake/share/cmake-3.6/Modules/FindGLEW.cmake:44 (find_package_handle_standard_args)
  source/CMakeLists.txt:5 (find_package)

FindGLEW.cmake是否可能损坏?我查看了另外两个FindXXXXX.cmake文件，它们就像雪花一样，每个雪花都很独特.因此，很难确定我是否遵循惯例.

Is it possible the FindGLEW.cmake is broken? I've looked at a couple of other FindXXXXX.cmake files and they are like snowflakes, each one pretty unique. So it's hard for me to say with any certainty that it's following convention.

推荐答案

查看

Looking in the sources, the package is looking for GLEW in relative paths. These relative paths are searched using different prefixes, including the content of the variable CMAKE_PREFIX_PATH:

的
• <prefix>/include，用于查找包含目录.
• <prefix>/lib表示find_library，用于查找库.

• <prefix>/include for find_path which is used to find include directories.
• <prefix>/lib for find_library which is used to find libraries.

假设存在C:/Program Files/glew/include和C:/Program Files/glew/lib，请将C:/Program Files/glew添加到您的CMAKE_PREFIX_PATH变量中.像这样:

Assuming C:/Program Files/glew/include and C:/Program Files/glew/lib exist, add C:/Program Files/glew to your CMAKE_PREFIX_PATH variable. Something like:

list(APPEND CMAKE_PREFIX_PATH "C:/Program Files/glew")
find_package(GLEW REQUIRED)

请注意以下几行:

include_directories(${GLEW_INCLUDE_DIRS})
link_libraries(${GLEW_LIBRARIES})

可以使用导入的目标

may be dropped using imported target Glew::Glew:

add_executable(foo ...)
target_link_libraries(foo Glew::Glew)
