首先说明如何修改或创建一个环境变量,使用set(ENV{<variable>} <value>) 指令用以声明,使用unset(ENV{<variable>})来清除某一个环境变量,其中ENV表示环境变量标志性前缀,variable指变量名称,value则为变量值,需要注意的是设定或读取环境变量时,都通过ENV前缀来访问环境变量,读取环境变量值时,要在ENV前加$符号;但i...
set(CMAKE_CXX_EXTENSIONS OFF) set(CMAKE_CXX_STANDARD_REQUIRED ON) 由于我们希望使用 Eigen 库,因此我们需要在系统上找到其头文件: 代码语言:javascript 复制 find_package(Eigen3 3.3 REQUIRED CONFIG) 我们包含CheckCXXCompilerFlag.cmake标准模块文件: 代码语言:javascript 复制 include(CheckCXXCompilerFlag) 我...
FASTDDS_STATISTICS是一个环境变量,用于配置 DomainParticipant 的统计信息数据写入器(DataWriters),前提是 CMake 选项FASTDDS_STATISTICS已启用。 关键点: 使用条件: 该环境变量仅在 CMake 选项FASTDDS_STATISTICS被启用的情况下有效。如果未启用此选项,设置该环境变量将不会产生任何效果。因此,在使用之前,请确保已正...

#5.set environment variable,设置环境变量,编译用到的源文件全部都要放到这里,否则编译能够通过,但是执行的时候会出现各种问题,比如"symbol lookup error xxxxx , undefined symbol" SET(TEST_MATH ${DIR_SRCS}) #6.add executable file,添加要编译的可执行文件 ...
This is the full path to the top level of the current CMake build tree. For an in-source build, this would be the same as CMAKE_SOURCE_DIR. CMAKE_BUILD_TOOL Tool used for the actual build process. This variable is set to the program that will be needed to build the output of C...
