使用带有空白的CMake的include_directories命令 [英] Using CMake's include_directories command with white spaces

问题描述

我正在使用CMake构建项目，并且有以下内容:

I am using CMake to build my project and I have the following line:

include_directories(${LLVM_INCLUDE_DIRS})

，在评估LLVM_INCLUDE_DIRS之后，其评估结果为:

which, after evaluating LLVM_INCLUDE_DIRS, evaluates to:

include_directories(C:\Program Files\LLVM\include)

问题在于，这被认为是两个包含目录，即"C:\ Program"和"Files \ LLVM \ include".

The problem is that this is being considered two include directories, "C:\Program" and "Files\LLVM\include".

有什么主意我该如何解决这个问题?我尝试使用引号，但没有用.

Any idea how can I solve this problem? I tried using quotation marks, but it didn't work.

编辑:原来问题出在文件llvm-3.0\share\llvm\cmake\LLVMConfig.cmake中.我用引号将以下路径括起来，问题已解决:

It turned out that the problem is in the file llvm-3.0\share\llvm\cmake\LLVMConfig.cmake. I enclosed the following paths with quotation marks and the problem was solved:

set(LLVM_INSTALL_PREFIX C:/Program Files/LLVM)
set(LLVM_INCLUDE_DIRS ${LLVM_INSTALL_PREFIX}/include)
set(LLVM_LIBRARY_DIRS ${LLVM_INSTALL_PREFIX}/lib)

推荐答案

在设置LLVM_INCLUDE_DIRS时，这很可能是错误，而不是include_directories的问题.

This is more likely to be an error at the point where LLVM_INCLUDE_DIRS is set rather than a problem with include_directories.

要对此进行检查，请尝试致电include_directories("C:\\Program Files\\LLVM\\include")-它应该可以正常工作.

To check this, try calling include_directories("C:\\Program Files\\LLVM\\include") - it should work correctly.

问题似乎是LLVM_INCLUDE_DIRS是在不使用引号的情况下构造的.尝试例如运行以下命令:

The problem seems to be that LLVM_INCLUDE_DIRS was constructed without using quotation marks. Try for example running this:

set(LLVM_INCLUDE_DIRS C:\\Program Files\\LLVM\\include)
message("${LLVM_INCLUDE_DIRS}")
set(LLVM_INCLUDE_DIRS "C:\\Program Files\\LLVM\\include")
message("${LLVM_INCLUDE_DIRS}")

输出为:

C:\Program;Files\LLVM\include
C:\Program Files\LLVM\include

请注意第一条输出行中的分号.这是一个包含2个项目的列表.

Note the semi-colon in the first output line. This is a list with 2 items.

因此解决此问题的方法是修改LLVM_INCLUDE_DIRS的创建方式.

So the way to fix this is to modify the way in which LLVM_INCLUDE_DIRS is created.
