描述

The current cmake completion does not suggest the -D arguments that are required when running --find-package. See also stackoverflow.

Essentially, when one uses --find-package, also -DNAME must be set. Otherwise cmake complains:

CMake Error at /usr/share/cmake-3.12/Modules/CMakeFindPackageMode.cmake:33 (message):
  Name of the package to be searched not specified.  Set the CMake variable
  NAME, e.g.  -DNAME=JPEG .

Further down the line one gets

CMake Error at /usr/share/cmake-3.12/Modules/CMakeFindPackageMode.cmake:37 (message):
  COMPILER_ID argument not specified.  In doubt, use GNU.

then

CMake Error at /usr/share/cmake-3.12/Modules/CMakeFindPackageMode.cmake:41 (message):
  LANGUAGE argument not specified.  Use C, CXX or Fortran.

and eventually

CMake Error at /usr/share/cmake-3.12/Modules/CMakeFindPackageMode.cmake:45 (message):
  MODE argument not specified.  Use either EXIST, COMPILE or LINK.

I.e. --find-package implies that -DNAME=, -DLANGUAGE=, -DCOMPILER_ID= and -DMODE= are provided. The possible values are spelled out in the error messages above.

I don't see how to add that myself to the current completion (given time constraints and priorities).

研究方向
Look at the existing cmake completion file (likely ` cmake`) in the repository. Add logic to suggest ` DNAME=`, ` DCOMPILER ID=`, ` DLANGUAGE=`, and ` DMODE=` options when ` find package` is present. The possible values are given in the error messages: NAME can be any package name, COMPILER ID can be GNU, Clang, etc., LANGUAGE can be C, CXX, Fortran, MODE can be EXIST, COMPILE, LINK. You may need to parse the existing completion to understand how to add these dynamically.
