How to Make cURL works with cmake

How to Make cURL works with cmake

Recently, I want to learn cURL, so downloaded it and compiled it, and use

cmake to manage the project, I wrote a CMakelists.txt as below:

cmake_minimum_required(VERSION 2.8)
project(curlTest)
find_package(CURL REQUIRED)
include_directories(${CURL_INCLUDE_DIR})
set(sources appMain.cpp)
add_executable(curlTest ${sources})
target_link_libraries(curlTest ${CURL_LIBRIRIES})

But it did not work, and cmake reported that it can not find cURL, I met

this situation before, so I set the environment variable for cmake like this:

set LIBCURL_ROOT= "cURL's path"

But it did not work neither, and I was confused, what was wrong with me, and

how could I make it works?

So I configured the environment variable CPLUS_INCLUDE_PATH to libcurl's

path, it did not work neither.

Finally, I open the file FindCURL.cmake and check content, I found that the

content didn't point the path of libcurl out, so I modified sentence in

FindCURL.cmake:

find_path(CURL_INCLUDE_DIR
NAMES curl/curl.h)

to

find_path(CURL_INCLUDE_DIR
NAMES curl/curl.h
PATHS $ENV{LIBCURL_ROOT}/include)

and the sentece in FindCURL.cmake

find_library(CURL_LIBRARY NAMES
curl
# Windows MSVC prebuilts:
curllib
libcurl_imp
curllib_static
# Windows older "Win32 - MSVC" prebuilts (libcurl.lib, e.g. libcurl-7.15.5-win32-msvc.zip):
libcurl)

to

and run:

cmkae .. -G "MinGW Makefiles", it worked.

The conclution:

1. don't trust the libraries so much.

2. think more.
