Strange library behaviour between HCBMP180 and BMP280 libraries

In my sketch, I include the HCBMP180 library:

#include "HCBMP180.h"

Works fine. However, if I copy the BME280 library into my libraries folder, I can no longer compile.
I get errors about something having to do with the BME280 library. I am not including it in my sketch, but for some reason it complains about it anyway.

I have attched the error dump and the sketch.

It's really got me baffled.

SIP.ino (2.02 KB)

Error.txt (1.54 KB)

Did you read the error message:

Error reading file (C:\Program Files (x86)\Arduino\libraries\BME280\library.properties:6): Invalid line format, should be 'key=value'

Your BME280 library is damaged in the library.properties file at line 6. How did you install that library?

I installed the one available in the library manager and it works flawlessly.

Well, I admit I did not spot that in the error dump. I do have a lot of trouble reading the 4 lines of text that are presented wihout any kind of formatting, like newline or CR characters. One of those lines is 1577 characters long, and the other is 292 characters long. I gave up trying to split it out into readable chunks about halfway through the long line.

What really had me fooled was the error itself, as I did not include it. Oh well.

Anyway, I see it now. Thanks for pointing it out.

As for installing it, I downloaded it from here and copied it into my libraries folder. I got it from a link in a posting here.

Never used the library manager before. I did just now, and asked it to install the library, but it doesn't show up in my libraries directory. Manager tells me it's installed, though. It shows up under "contributed libraries" when I ask it to "Include Library", and its examples show up when I look at Files>Examples, but I don't know where it actually lives.

Any idea where I might find it?

Anyway, sorry for the rant, but I'm a bit frustrated, and I really do appreciate your help. My sketch now compiles.

You did copy your downloaded library to the wrong folder. The libraries folder in the program folder should contain only the default libraries. The user installed libraries go to the libraries subfolder of the Sketchbook folder, on your system that seems to be "L:\Arduino\SketchBook\libraries".
Don't forget to delete the folder you installed youself as it seems to be damaged.
