CMake报错集锦

一、报错1

-bash: pybind11-config: command not found
CMake Error at CMakeLists.txt:33 (find_package):
  By not providing "Findpybind11.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "pybind11",
  but CMake did not find one.

  Could not find a package configuration file provided by "pybind11" with any
  of the following names:

    pybind11Config.cmake
    pybind11-config.cmake

  Add the installation prefix of "pybind11" to CMAKE_PREFIX_PATH or set
  "pybind11_DIR" to a directory containing one of the above files.  If
  "pybind11" provides a separate development package or SDK, be sure it has
  been installed.


-- Configuring incomplete, errors occurred!

这类错误经常发送，分两步解决：
第一步：
找到对应的包，以这个为例：

sudo find / -name pybind11Config.cmake

然后一般是在python的路径下（因为是python的包），比如这里就找到了：

/home/nvidia/venv/lib/python3.6/site-packages/pybind11/share/cmake/pybind11/pybind11Config.cmake

第二步：
在CMakeLists.txt文件中的find_package(pybind11 REQUIRED)新增：

set(CMAKE_PREFIX_PATH /home/nvidia/venv/lib/python3.6/site-packages/pybind11)
set(pybind11_DIR /home/nvidia/venv/lib/python3.6/site-packages/pybind11/share/cmake/pybind11/pybind11Config.cmake)

就修改OK了~ 按照之前的CMake命令重新执行即可。
