+Subject: [PATCH] Don't assume cryptopp is system-wide installed
+
+The current build system adds "-isystem /usr/include/$(CRYPTOLIB)" to
+AM_CPPFLAGS, but this is wrong because cryptopp might not be installed
+in this location. Instead, the build system should simply include
+<cryptopp/...> or <crypto++/...> and rely on the compiler include
+path.
+
+The tricky part is that it can be <cryptopp/...> or <crypto++/...>. To
+solve this, we use a solution similar to the one used in
+https://github.com/bingmann/crypto-speedtest/blob/master/m4/cryptopp.m4
+and
+https://github.com/bingmann/crypto-speedtest/blob/master/src/speedtest_cryptopp.cpp:
+the configure script fills in a variable called
+CRYPTOLIB_HEADER_PREFIX, and we use that in the C++ code to include
+the right header file.
+
+It is worth mentioning that doing #include
+<CRYPTOLIB_HEADER_PREFIX/foobar.h> doesn't work, and we have to use an
+intermediate #define'd constant to overcome this C preprocessor
+limitation.
