GL/glew.h:在glew.c中没有这样的文件或目录

Question

当我试图编译我的程序时，我得到了这个错误

C:...CLionProjectsRadixvendorsglew-2.1.0srcglew.c:34:10: fatal error: GL/glew.h: No such file or directory
#include <GL/glew.h>
^~~~~~~~~~~

错误在库代码中，我做错了什么？

我的项目结构如下：

Radix
|- Radix-core
|- cpp code..
|- vendors
|- CMakeLists.txt
|- glew-2.1.0
|- Other libs..
- CMakeLists.txt

CMakeLists.txt(只显示零件(

# Including GLEW

target_link_libraries(Radix ${ALL_LIBS})

### GLEW ###
set(GLEW_HEADERS)
set(GLEW_SOURCE glew-2.1.0/src/glew.c)
set(GLEW_INCLUDE glew-2.1.0/include)
add_library(GLEW_210 ${GLEW_SOURCE} ${GLEW_INCLUDE})
target_link_libraries(GLEW_210 ${OPENGL_LIBRARY} ${EXTRA_LIBS})

Answer 1

将include目录添加到GLEW_210的源文件中不会有任何作用。将其添加为PUBLIC包含目录，因此glew.c的编译也可以访问glew标头：

target_include_directories(GLEW_210 PUBLIC glew-2.1.0/include)

这也将include目录传播到与GLEW_210链接的任何目标，因此您可以在主CMakeLists.txt 中删除include_directories语句
