[petsc-users] CMake error in PETSc

[Yingjie Wu]

Dear Petsc developers
Hi,
Because I use some external library files, I want to compile the PETSc
program with CMake. I follow the library search program
https://github.com/CoolProp/CoolProp/blob/b493de51a44078e4f5bbb8712e89305fd91f8b85/CMakeLists.txt
recommended
on GitHub. And wrote a cmakelist.txt:

cmake_minimum_required(VERSION 2.8.11)
project(example01cmke)
add_executable(example01cmke ex1.cpp)
set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake/modules)
find_package(PETSc)
include_directories(${PETSC_INCLUDE_DIR})
target_link_libraries(example01cmke ${PETSC_LIBRARIES})

My document relationships are:

 After compiling with cmake.. and make, there is an error message:

I don't know how to solve this problem,ex1.cpp is the first example in SNES
tutorial, please give me some advice.

Best regards,
