when I run the last step, colon build, it occur
CMake Error at CMakeLists . txt :187( find _ package ):
By not providing " Findmimick _ vendor . cmake " in CMAKE MODULE PATH this
project has asked CMake to find a package configuration file provided by " mimick _ vendor ", but CMake did not find one .
Could not find a package configuration file provided by " mimick _ vendor " with any of the following names :
mimick vendorConfig . cmake
mimick _ vendor - config . cmake
Add the installation prefix of " mimick vendor " to CMAKE PREFIX PATH or set " mimick _ vendor _ DIR " to a directory containing one of the above files . If " mimick _ vendor " provides a separate development package or SDK , be sure it has been installed .
