[dpdk-dev] [PATCH v2 1/4] net/cxgbe: use relative paths for including header files

[Rahul Lakkireddy]

The Intel C++ compiler is not able to locate the header files without
relative paths in Windows build. Following errors are seen for these
header files.

C:\> base\common.h(9): error : cannot open source file "cxgbe_compat.h"
        #include "cxgbe_compat.h"
                                 ^
[...]

Fix by explicitly stating header file location using relative paths.
Also, remove automatically including header files for Linux, to keep
it consistent across both OS.

Build Environment:
1. Target OS: Microsoft Windows Server 2016
2. Compiler: Intel C++ Compiler from Intel Parallel Studio XE 2019 [1]
3. Development Tools:
   3.1 Microsoft Visual Studio 2017 Professional
   3.2 Windows Software Development Kit (SDK) v10.0.17763
   3.3 Windows Driver Kit (WDK) v10.0.17763
