我正在尝试让我的cmake项目自动编译,但是当我的路径包含空格时我遇到了一些困难。
这是我的命令行(windows命令提示符)
C:\Code\codetrainerplugins-build>type %CODETRAINER_PATH%\include\common\exportapi.h
#pragma once
... the file is found ...
这是我的CMakeLists.txt文件:
CMAKE_MINIMUM_REQUIRED (VERSION 2.6)
PROJECT (CodeTrainerPlugins)
MESSAGE("$ENV{CODETRAINER_PATH}")
FIND_PATH (CODETRAINER_FRAMEWORK_PATH
NAMES include/common/ExportApi.h
PATHS
ENV CODETRAINER_PATH
)
if (CODETRAINER_FRAMEWORK_PATH)
MESSAGE(STATUS "CodeTrainer Framework found at: ${CODETRAINER_FRAMEWORK_PATH}")
else()
MESSAGE(FATAL_ERROR "CodeTrainer Framework not found")
endif()
ADD_SUBDIRECTORY(function)
ADD_SUBDIRECTORY(test)
这是CODETRAINER_PATH变量包含空格时的输出(请参阅路径中的空格):
C:\Code\codetrainerplugins-build>echo %CODETRAINER_PATH%
"C:\Code Trainer"
C:\Code\codetrainerplugins-build>
C:\Code\codetrainerplugins-build>cmake ..\codetrainerplugins
-- Building for: Visual Studio 10
"C:\Code Trainer"
CMake Error at CMakeLists.txt:16 (MESSAGE):
CodeTrainer Framework not found
-- Configuring incomplete, errors occurred!
See also "C:/Code/codetrainerplugins-build/CMakeFiles/CMakeOutput.log".
C:\Code\codetrainerplugins-build>
但是当使用的路径没有空格时,一切正常(见下文):
C:\Code\codetrainerplugins-build>echo %CODETRAINER_PATH%
C:\CodeTrainer
C:\Code\codetrainerplugins-build>cmake ..\codetrainerplugins
C:\CodeTrainer
-- CodeTrainer Framework found at: C:/CodeTrainer
-- Configuring done
-- Generating done
-- Build files have been written to: C:/Code/codetrainerplugins-build
C:\Code\codetrainerplugins-build>
您对如何解决此问题有任何解决方案吗?
我正在使用cmake 2.8.12 for Windows。
谢谢, 尤利安

我必须承认,我本来期望这也“正常工作”,但它看起来实际上是CODETRAINER_PATH
中的引号,当它有空格导致问题时。
在定义环境变量CODETRAINER_PATH
时要么不添加引号,要么修改你的CMake代码:
STRING(REPLACE "\"" "" CODETRAINER_PATH_WITHOUT_QUOTES $ENV{CODETRAINER_PATH})
FIND_PATH(CODETRAINER_FRAMEWORK_PATH
NAMES include/common/ExportApi.h
PATHS ${CODETRAINER_PATH_WITHOUT_QUOTES}
)
