使用CMake链接GLEW [英] Linking against GLEW with CMake

问题描述

我的项目依赖于GLEW，是用CMake构建的，所以我从这里找到FindGLEW.cmake http://code.google.com/p/nvidia-texture-tools/source/browse/trunk/cmake/FindGLEW.cmake?r= 96 并在我的CMakeLists.txt中写入 find_package（GLEW REQUIRED）。问题是，我在一个集群PC上工作的几个版本的GLEW可用。一个版本存储在 / usr / lib 中，这不是最新的。最新版本存储在 / opt / local / lib64 中。这是我想链接的版本。所以我添加了GLEW_LIBRARY路径下FindGLEW.cmake的路径。问题是makefile总是链接到旧的版本，但我需要最新的版本（1.7）使用像 GL_PATCHES ， GL_PATCH_PARAMETERS 等。我可以一些如何强制CMake使用较新的版本，就像这是FindBoost.cmake的情况。一个解决方案是擦除旧的，但这不是一个选择。我也改变了GLEW_LIBRARY列表中的路径的顺序，但是没有成功。

在我的旧Makefile我只是写了 LDDFLAGS = -L / opt / local / lib64 -lGLEW 所以路径是绝对清楚的，但现在与CMake我想使用查找功能，但希望更喜欢一个特定的版本。

<我使用这个链接静态链接到在特定位置的自定义编译GLEW库：

 >  #GLEW libraries 
 add_library（glew_static STATIC IMPORTED）
 set_target_properties（glew_static PROPERTIES 
 IMPORTED_LOCATION /home/ryan/DevLibrary/glew-1.9.0/lib/libGLEW。 a）
 target_link_libraries（smolder glew_static）
  

>

  find_package（GLEW REQUIRED）
  

您也可以使用共享库，只需从add_library中删除STATIC关键字。

My project depends on GLEW and is built with CMake, so i took the FindGLEW.cmake from here http://code.google.com/p/nvidia-texture-tools/source/browse/trunk/cmake/FindGLEW.cmake?r=96 and wrote find_package(GLEW REQUIRED) in my CMakeLists.txt. Problem is that i am working on a cluster PC were several versions of GLEW are available. One version is stored in /usr/lib which is not the latest. the latest version is stored in /opt/local/lib64. this is the version i want to link against. so i added the path to the FindGLEW.cmake under the GLEW_LIBRARY paths. the problem is that the makefile always links against the older version, but i need the newest version (1.7) for using stuff like GL_PATCHES, GL_PATCH_PARAMETERS and so on. can i some how force CMake to use the newer version like it is the case with FindBoost.cmake. one solution is to erase the older one's but this is not an option. i also changed the order of the paths in the GLEW_LIBRARY list, but without success.

in my old Makefile i just wrote LDDFLAGS = -L/opt/local/lib64 -lGLEW so the path is absolutely clear, but now with CMake i want to use the find feature, but want to prefer a specific version.

解决方案

I use this to link statically to a custom compiled GLEW lib at a specific location:

#GLEW libraries
add_library(glew_static STATIC IMPORTED)
set_target_properties(glew_static PROPERTIES
    IMPORTED_LOCATION /home/ryan/DevLibrary/glew-1.9.0/lib/libGLEW.a)
target_link_libraries(smolder glew_static)

With this in place you can remove

find_package(GLEW REQUIRED)

You can use this with shared libraries as well, simply remove the STATIC keyword from add_library.
