ubuntu cmake…中出现的问题
在写一个helloworld的小工程，然后cmakelists如下
cmake_minimum_required( VERSION 2.8)
project (hello world)
add_executable(helloworld main.cpp)执行cmake…
结果出现报错
CMake Error: Could not find cmake module file: CMakeDetermineworldCompiler.cmake
CMake Error: Error required internal CMake variable not set, cmake may not be built correctly.
Missing variable is:
CMAKE_world_COMPILER_ENV_VAR
CMake Error: Error required internal CMake variable not set, cmake may not be built correctly.
Missing variable is:
CMAKE_world_COMPILER
CMake Error: Could not find cmake module file: /home/south/code/123/CMakeFiles/3.16.3/CMakeworldCompiler.cmake
CMake Error at CMakeLists.txt:2 (project):
No CMAKE_world_COMPILER could be found.
Tell CMake where to find the compiler by setting the CMake cache entry
CMAKE_world_COMPILER to the full path to the compiler, or to the compiler
name if it is in the PATH.
CMake Error: Could not find cmake module file: CMakeworldInformation.cmake
CMake Error: CMAKE_world_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!
See also "/home/south/code/123/CMakeFiles/CMakeOutput.log".上网找了很多的相关问题，有说需要用yum安装cmake的还有说是版本问题的
一一试过都不行，最后发现问题出在project（）里面不能有空格。。。。。。。。
空格删掉最终cmake …成功
