我试图建立一个使用 PETSc 的项目。为此，我从https://github.com/jedbrown/cmake-modules下载了 cmake 模块。当我尝试构建项目时，我收到以下错误消息：
(...)

我已经下载了 openMPI（cygwin 包）并使用以下方法构建了 Petsc：
"--prefix="where_petsc_will_be_installed" --with-clanguage=C --with-mpi --with-cc=mpicc --with-cxx=0 --with-fc=0 --download-f2cblaslapack --with-调试=是”
并使用以下方式导出路径：
export PETSC_DIR="where_petsc_is_installed"
export PETSC_ARCH=""
export PATH=${PATH}:${PETSC_DIR}/lib:${PETSC_DIR}/bin
为什么我会收到这些错误以及如何解决它们？
