EXISTS函数在CMake中主要用于检查文件或目录是否存在。它的基本语法是if(EXISTS <file-or-directory>),其中<file-or-directory>是你想要检查的文件或目录的路径。 除了基本的文件和目录存在性检查,EXISTS函数还可以与其他CMake命令结合使用以实现更复杂的功能。例如: 你可以使用if(NOT EXISTS <file-or-directory>)来...
数值比较,比如:EQUAL、LESS、GREATER等; 布尔运算,AND、OR、NOT; 路径判断,比如:EXISTS、IS_DIRECTORY、IS_ABSOLUTE等; 版本号判断;等等; 使用小括号可以组合多个条件语句,比如:(cond1) AND (cond2 OR (cond3))。 对于常量: ON、YES、TRUE、Y和非0值均被视为True; 0、OFF、NO、FALSE、N、IGNORE、空字符...

# For build in directory: xxx/build # It was generated by CMake: yyy/cmake # You can edit this file to change values found and used by cmake. # If you do not want to change any of the values, simply exit the editor. # If you do want to change a value, simply edit, save,...
If the target is not followed by any name, make looks for .make.state file in the current working directory. .MAKE_VERSION: A target-entry of the form: .MAKE_VERSION: VERSION−number enables version checking. If the version of make differs from the version indicated by a string like ...
if (NOT WIN32) set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib) set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib) set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/demo) else() set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/paddle_deploy) ...
How about this one-liner (in bash): mkdir --parents ./some/path/; mv yourfile.txt $_ Breaking that down: mkdir --parents ./some/path # if it doesn't work; try mkdir -p ./some/path creates the directory (including all intermediate directories), after whi...
echo "This line will always print, because the file hello does not exist." 这里已经有很多东西可以吸收了。让我们分解一下: 我们有一个目标叫做hello 这个目标有两个命令 此目标没有先决条件 然后我们将运行make hello. 只要hello文件不存在,命令就会运行。如果hello确实存在,则不会运行任何命令。
Check if it exists, then use ${CMAKE_COMMAND} instead of cp for good compatibility practice: if(NOT EXISTS ${LIB_DEST}) add_custom_command( OUTPUT ${LIB_DEST} COMMAND ${CMAKE_COMMAND} -E copy ${LIB_SOURCE} ${LIB_DEST} COMMENT "Copying libmylib.a to external_dependencies/" ) add...
The above command makes the shell run the script named configure which exists in the current directory. The configure script basically consists of many lines which are used to check some details about the machine on which the software is going to be installed. This script checks for lots of ...
