apt-get

install by apt-get, but we can not use find_package(Poco) because no /usr/local/lib/cmake/Poco/PocoConfig.cmake installed.

sudo apt-get install libpoco-doc libpoco-dev

compile from source

wget https://pocoproject.org/releases/poco-1.8.1/poco-1.8.1.tar.gz

#Install dependences
sudo apt-get install openssl libssl-dev
sudo apt-get install libiodbc2 libiodbc2-dev
sudo apt-get install libmysqlclient-dev

cd poco-1.8.1
#sudo ./configure --omit=Data/ODBC,Data/MySQL --no-tests --no-samples --shared
cd build 
cmake-gui ..
sudo make -j8 
sudo make install

OK. we install headers to /usr/local/include/Poco and libraries to /usr/local/lib/

$ ls /usr/local/libPoco*.so 

/usr/local/lib/libPocoFoundation.so  /usr/local/lib/libPocoNet.so   /usr/local/lib/libPocoXML.so
/usr/local/lib/libPocoJSON.so        /usr/local/lib/libPocoUtil.so

we install cmake files to /usr/local/lib/cmake/Poco

$ ls /usr/local/lib/cmake/Poco

PocoConfig.cmake                     PocoJSONTargets.cmake          PocoUtilTargets.cmake
PocoConfigVersion.cmake              PocoJSONTargets-release.cmake  PocoUtilTargets-release.cmake
PocoFoundationConfig.cmake           PocoNetConfig.cmake            PocoXMLConfig.cmake
PocoFoundationConfigVersion.cmake    PocoNetConfigVersion.cmake     PocoXMLConfigVersion.cmake
PocoFoundationTargets.cmake          PocoNetTargets.cmake           PocoXMLTargets.cmake
PocoFoundationTargets-release.cmake  PocoNetTargets-release.cmake   PocoXMLTargets-release.cmake
PocoJSONConfig.cmake                 PocoUtilConfig.cmake
