Compile Error #include expects "FILENAME" or <FILENAME>

[Nexus1212]

There is a Bug in the compiling of the MD5.h files.
Path:
C:\Sloeber\arduinoPlugin\packages\esp32\hardware\esp32\1.0.4\tools\sdk\include\mbedtls\mbedtls

see issue:

1. Include md5.h throws compile error #include expects "FILENAME" or <FILENAME> espressif/arduino-esp32#1327
2. quoted strings from the command line not always working #1028

If I changed the MD5.h:
#if !defined(MBEDTLS_CONFIG_FILE)
#include "config.h"
#else
#include MBEDTLS_CONFIG_FILE
#endif

to:
#if !defined(MBEDTLS_CONFIG_FILE)
#include "config.h"
#880
#define VAL(str) #str
#define TOSTRING(str) VAL(str)
#include TOSTRING(MBEDTLS_CONFIG_FILE)
#endif

it works! Do you know a better solution?

Do you know a better solution?

From my point of view the workaround is the way it should be done.

PR of this workaround can be found here: espressif/arduino-esp32#4159

The workaround includes a check to see if it is being compiled by eclipse, and does the workaround, and if not to use the normal mode. This check is needed to be sure that the original Arduino IDE works with the same toolchain without a new bug caused by the workaround.

The above OP workaround causes this bug in Arduino IDE:

In file included from 
Arduino/hardware/espressif/esp32/libraries/WebServer/src/WebServer.cpp:32:0:
Arduino/hardware/espressif/esp32/tools/sdk/include/mbedtls/mbedtls/md5.h:38:55: fatal error: \"mbedtls/esp_config.h\": No such file or directory
compilation terminated.

The PR adds checks to prevent this bug.

As far as I know this is fixed in the latest Sloeber and no workaround is needed

Combination of single quotes, double quotes and / should work:
make CFLAGS='-DMBEDTLS_CONFIG_FILE=\"mbedtls_config.h\"'
