CMake Error at cmake/abseil-cpp.cmake:38 (find_package):
  Could not find a package configuration file provided by "absl" with any of
  the following names:

    abslConfig.cmake
    absl-config.cmake

  Add the installation prefix of "absl" to CMAKE_PREFIX_PATH or set
  "absl_DIR" to a directory containing one of the above files.  If "absl"
  provides a separate development package or SDK, be sure it has been
  installed.
Call Stack (most recent call first):
  CMakeLists.txt:191 (include)

原因，是没有安装absl

解决方法：

git clone https://github.com/abseil/abseil-cpp.git

在CMakeLists.txt中加上一句：

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

编译

cmake -DBUILD_SHARED_LIBS=ON -L CMakeLists.txt && make

安装

sudo make install
