linux环境下编译jsoncpp的cmake错误解决

错误信息

linux下在解压的jsoncpp文件夹中执行：

sudo cmake CMakeList.txt

先看一下报错情况：

-- The CXX compiler identification is GNU 9.4.0
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info

# jsoncpp should not be configured & built in the jsoncpp source directory
# You must run cmake in a build directory.
# For example:
# mkdir jsoncpp-Sandbox ; cd jsoncpp-sandbox
# git clone https://github.com/open-source-parsers/jsoncpp.git # or download & unpack the source tarball
# mkdir jsoncpp-build
# this will create the following directory structure
#
# jsoncpp-Sandbox
#  +--jsoncpp
#  +--jsoncpp-build
#
# Then you can proceed to configure and build
# by using the following commands
#
# cd jsoncpp-build
# cmake ../jsoncpp # or ccmake, or cmake-gui 
# make
#
# NOTE: Given that you already tried to make an in-source build
#       CMake have already created several files & directories
#       in your source tree. run 'git status' to find them and
#       remove them by doing:
#
#       cd jsoncpp-Sandbox/jsoncpp
#       git clean -n -d
#       git clean -f -d
#       git checkout --

初步分析

根据上述信息分析：

不能在解压的源文件中进行编译，于是按照上述要求进行目录创建。

结果：失败，仍是相同的报错

将CMakeList.txt的报错位置注释掉（目前暂不清楚副作用，如有更优方案欢迎提出）

随后进行编译：

sudo cmake CMakeList.txt
