Error in make install

I used Cmake for generating the build files, but when I make install appeared this message about the using of zxing::bolean.

C:\Users\rogge\Desktop\nuevo\zxing-cpp-master\build>mingw32-make install

I wanna know what I have to change. Please help.

I am wondering if your error is the same as mine.
