ROS2 colcon build出现Could not find a package configuration file provided by “ament_cmake”
问题描述
在编译ROS2时，采用colcon build编译，出现
CMake Error at CMakeLists.txt:19 (find_package):
By not providing "Findament_cmake.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"ament_cmake", but CMake did not find one.
Could not find a package configuration file provided by "ament_cmake" with
any of the following names:
ament_cmakeConfig.cmake
ament_cmake-config.cmake
Add the installation prefix of "ament_cmake" to CMAKE_PREFIX_PATH or set
"ament_cmake_DIR" to a directory containing one of the above files. If
"ament_cmake" provides a separate development package or SDK, be sure it
has been installed.
解决办法：
将原来的指令
colcon build
修改为
source /opt/ros/foxy/setup.bash && colcon build --symlink-install
