cpttrend.cpp:142:27: error: 'PI' was not declared in this scope

Hi,

Hope this email finds you well. I hope to install R package "techchart". I have followed all instruction like installed the Rtools and devtools before running the devtools::install_github("prodipta/techchart"). However I got the following error when running the code:

From my understanding of the error description, seems the PI was not defined in the c++. Please could you shed some light about if I have done things wrong with the installation? Thank you very much.

download the code, replace PI with M_PI and use devtools::install_local()
