https://github.com/powervr-graphics/Native_SDK/blob/master/BUILD.rst

git clone https://github.com/powervr-graphics/Native_SDK.git
cd Native_SDK
mkdir build
cd build
cmake ..
cmake --build .

(1)error:"CMake 3.10 or higher is required.  You are running version 3.5.1"

https://blog.csdn.net/mengyu_0317/article/details/106868041

cd cmake-3.16.8
./configure
make
make install
cmake --version

注意：cmake默认安装到了/usr/local/bin/下，所以cmake命令需要改为：
/usr/local/bin/cmake ..

(2)error:"Could NOT find OpenSSL"

apt-get install libssl-dev

确认网址是对的！(https://github.com/zeux/pugixml/releases/download/v1.10/pugixml-1.10.tar.gz)

"SSL connect error"网上查不出解决方法

但是pugixml-1.10.tar.gz包可以从网上手动下载(https://github.com/zeux/pugixml/releases/tag/v1.10)，那么尝试手动处理：

[1]将/home/hanyuhang/src/powervr-sdk/Native_SDK/external/pugixml目录下的CMakelist删除

/usr/local/bin/cmake ../

报错：

 [2]修改cmake命令：/usr/local/bin/cmake ../ -DPVR_WINDOW_SYSTEM=X11
cmake配置成功 

编译：/usr/local/bin/cmake --build .

报错：

将下载的pugixml-1.10.tar.gz解压到/home/xxx/src/powervr-sdk/Native_SDK/build/external/pugixml/src
解压：

 编译pugixml：

mkdir build
cd build
/usr/local/bin/ cmake ../
make
make install

 [3]再继续编译powervr

/usr/local/bin/cmake --build .

报错：cannot find -lpugixml

cp /usr/local/lib/libpugixml.a /usr/lib/
[4]再继续编译powervr
/usr/local/bin/cmake --build .
编译完成：
