windows下CMake fdk-aac

《音视频应用开发系列文章目录》

前言

在Linux下fdk-aac有编译脚本，可以轻松的编译之。但是在Windows下木有，这边创建fdk-aac cmake工程使得fdk-aac能cmake跨平台编译。这里使用Windows下的MSVC编译器编译。

准备

下载fdk-aac源码(本文使用的版本是fdk-aac-2.0.1)

CMake工具(本文使用的版本是cmake-3.16.0-rc4-win64-x64)

CMake fdk-aac

创建CMakeLists.txt文件

在fdk-aac源码根目录下创建CMakeLists.txt文件，输入以下内容，具体细节已经注释的很清楚。

# A cmake file for compile fdk-aac
# Author: kaychan
# Mail: [email protected]
#
# fdk-aac download: http://www.linuxfromscratch.org/blfs/view/svn/multimedia/fdk-aac.html
# fdk-aac version: fdk-aac-2.0.1
# cmake version: cmake-3.16.0-rc4-win64-x64

# Disable in-source builds to prevent source tree corruption.
if(" ${CMAKE_SOURCE_DIR}" STREQUAL " ${CMAKE_BINARY_DIR}")
  message(FATAL_ERROR "
FATAL: In-source builds are not allowed.
       You should create a separate directory for build files.
")
endif()
