自定义接口编译报错

[3279725327]

CMake Error at CMakeLists.txt:11 (find_package):
By not providing "Findexample_ros2_interfaces.cmake" in CMAKE_MODULE_PATH
this project has asked CMake to find a package configuration file provided
by "example_ros2_interfaces", but CMake did not find one.

Could not find a package configuration file provided by
"example_ros2_interfaces" with any of the following names:

example_ros2_interfacesConfig.cmake
example_ros2_interfaces-config.cmake

Add the installation prefix of "example_ros2_interfaces" to
CMAKE_PREFIX_PATH or set "example_ros2_interfaces_DIR" to a directory
containing one of the above files. If "example_ros2_interfaces" provides a
separate development package or SDK, be sure it has been installed.

@3279725327 在 自定义接口编译报错 中说：

example_ros2_interfaces

检查代码中是否有 find_package(example_ros2_interfaces)

@小鱼 好的谢谢

@3279725327 想问你你解决这个问题了吗，我检查过后依然无法编译
